First I want to apologize for the previous post of this video. I had not realized that the youtube poster was belittling the 787 delays. In my rush to post I failed to connect the dots. I appologize.

I did not post the video on Youtube so you can direct any complaints about the title to Youtube. Not me.

That said, I have not seen a 787 wing load test video posted here. So I am posting what I found.

This is a video of the wing load test from Novermber 2008.

I wonder how far they got beyond the 150% threshold before it broke.

Darn, I was kinda hoping the wing tips really would touch each other.  Silly

Still, good to see it was more than capable of meeting the requirements.  thumbsup

From all the clapping, looks like they got past it. Couldn't listen to it because I'm in a "quiet zone". Did they announce where it passes the threshold?



Of all the things to worry about... the Wookie has no pants.

This wasn't the entire wing. This was the wing box test.

That's why we're here.

I thought they were not going to test the wing to breakage.

The wing test everybody's waiting for will be the final static frame test where they bend the complete wing on the plane. Boeing can't seem to make up their mind if they'll break it or not, assuming it makes it past the 150%.

Ideally, just past it. If it's too far beyond, then more weight could have been saved.



Looks like I picked the wrong week to quit posting...

That was basically why I asked the question. 151% would be just about perfect, wouldn't it?

Boeing didn't want to break the wing due to the million dollar clean up bill that would have resulted afterwards.

From memory this was due to the way CFRP exploded into small fragments when broken, as opposed to a metal wing, which would've just snapped.

I'm guessing he's referring to the construction materials (CFRP), though I understand that the A380's wingbox also contains a significant amount of CFRP in it's construction.

Is the 787 wingbox completely (or more then say around 80%) CFRP?
